Not only are comments working fine, but there is a system in place to keep spam and trolls in check (although with the loss of @wang).
What other site has managed to accomplish this, while at the same time monetarily reward users for commenting with value?
I had begun to lose hope as a certain frequent "troll" started making my life miserable and quite a few others. I originally would have tried to rip him a new one, but through learning from Rok-Sivante's open letter to the hacker decided to put myself in the "trolls" shoes (however filthy they might be).
The next day the reputation system dropped and his comments were made invisible unless you clicked to see and his posts were greyed out. Absolutely brilliant way to work on a decentralized platform. He isn't silenced, but his vocal cords have been removed and he now has a whisper, which was the result of karma.
He still can slowly work his way back into a reputation that allows more people to see his content.
This is the opposite of what Twitter did with Milo Yiannopoulos Twitter Permanently Suspends Conservative Writer Milo Yiannopoulos. And @dollarvigilante hinted Milo may be coming to steemit.
And I am working on many more even bigger names. I'm currently trying to convince a friend named Milo, amongst others.
This could be huge, since a centralized platform silenced someone for what I felt was a very minor tweet.
That being said, the way comments have evolved, I have confidence that the "page rank" algorithm or any other idea that gets rolled out in the near future will be innovative and solve the current problem of scalability and voting from a single account by distributing voting to trusted people instead of one. Because even if you can have multiple people log into one account, the many different voters will still use the same voting power of the users account (unless something else has been implemented).
Great minds are working on this. From the hack, to the comment section changes, to the reputation system, developers have performed far better than I could have hoped and this is only BETA!
